Neptune's sidereal period or true orbital period.
60,190.03[5] days
164.79 years
Venus has a sidereal period (orbital period relative to distant stars) of approximately 224.7 Earth days. This means it takes Venus about 224.7 days to complete one orbit around the Sun.
The sidereal rotation period of Mars - one spin on its axis relative to background stars, is 24.623 hours. This is very similar to the earths sidereal rotation period.
Mercury has the 2nd longest "sidereal day" with a sidereal rotation period of 58.646 Earth days. The longest "sidereal day" day is Venus, with a sidereal rotation period of 243.018 Earth daysIf you use the "solar day" as your definition of "day", the order is reversed. Mercury then has the longest day and Venus has the second longest day.
Astronomers use the term "sidereal period" to describe the time it takes for a planet to orbit the sun relative to the stars. Sidereal periods are measured based on the apparent motion of a planet against the background of fixed stars rather than against the sun. This allows for more precise measurements of a planet's orbital period.
The sidereal day is the period of Earth's axial rotation. It's the same at every place on Earth on every day of the year. It's 23hours 56minutes 4.1seconds long. (seconds rounded)
The sidereal rotation period is 9.925 hours

Earth's sidereal period is 1 year or about 365.25 days ========= Whoever posted the previous answer shouldnt have wasted their time propagating lies and stupidity. What a moron who posts answers when they should know that they dont even know the answer. The Earth's Sidereal Period is 366.242 days, approximately.
11.8565 sidereal years.
23hours 56minutes 4seconds (rounded)
686.980 earth days, sidereal period; 779.94 earth days, synodic period.
Venus has a sidereal period (orbital period relative to distant stars) of approximately 224.7 Earth days. This means it takes Venus about 224.7 days to complete one orbit around the Sun.
Earth The sidereal rotational period of Mars is 1.025 957 days (ie 24.62296 hours) The sidereal rotational period of Earth is 0.99726968 day (ie 23h 56m 4.100s)
The sidereal rotation period of Mars - one spin on its axis relative to background stars, is 24.623 hours. This is very similar to the earths sidereal rotation period.
The length of a Martian day is equal to 1.027491204 Earth days. The length of one sidereal Martian year is equal to 1.880791 sidereal Earth years.
